upgrade from 1.9 to 2.1 and problem with visibility

[pecito]

Hi all,

today i upgraded two nodes from 1.9 to version 2.1
and there is strange problem.
two of our servers can't be reached from outside.
And both servers have installed cpanel, on the second is only dns version.
With other servers that work with debian or ubunt there isn't any kind of problem.

In advanced when i start migration with the script downloaded from proxmox,
list some kind of error with vzct and dad packages.
I made after that apt-get update , apt-get dist-upgrade
and next start the script again, after that the upgrade was successfull.
reboot the servers and made ./pve-upgrade-1.9-to-2.0 --import after reboot.
I think that the old vps will be restored, but not.
and after that, i made vzrestore of all old vps(before upgrade).

Pleace help because i just don't now what to do.

i found that the problem is somewhere in csf firewall
because when i stop it , all is ok.

i made configuration i /etc/vz/vz.conf
about iptables modules.
After reload of vz or reboot the server is still invisible.
